Uso y aplicación
USOS
Used where excellent chemical resistance to salt and fresh water, petroleum products, crude oil, alkalis and weak acids is required, particularly in heavy industrial atmospheres.
PREPARACIÓN DE SUPERFICIE Y APLICACIÓN
New concrete must be cured for at least 28 days; surface moisture must not exceed 4%. Remove weak surface layers, laitance, oil, curing compounds and old coating residues by milling, shot-blasting or diamond grinding; remove the dust with an industrial vacuum. Repair cracks and holes with epoxy repair mortar. Prime the surface with 646 Novolac Epoxy Concrete Primer. Mix components A and B with a low-speed mechanical mixer until homogeneous (at least 2–3 minutes) and apply the mix within its pot life. Spread with a squeegee and notched trowel. Ambient and floor temperature must be between +10 °C and +30 °C and relative humidity below 80%; floor temperature must be kept at least 3 °C above the dew point.
ÁREAS DE APLICACIÓN
→ Chemical, Petrochemical and Treatment
Technical data are average values at 20 °C and 65% relative humidity. Coverage varies with surface roughness, application method and film thickness. Consult the Gen Boya technical team for project-specific system design.
